Abstract：
Briefly reviews the development history of allowable air leakage standards and codes for metallic ducts at home and abroad, analyses the relevant requirements of the current design and construction standards for allowable air leakage control in China, and compares them with the allowable air leakage control indexes of typical foreign standards. Based on the investigation data, puts forward some suggestions to check the tightness of air ducts during design and construction using allowable air leakage.
